cryogenic refrigerant
Thread Content
What are the refrigerants that can reach minus 100 degrees? ? ?
Coolants at around minus 100 degrees Celsius typically include dichloromethane (R30) and chlorofluoromethane (R11). The solidification temperature of R30 is -97°C, and its suitable temperature range is -50 to -90℃ ； The solidification temperature of R11 is -111°C, and its suitable temperature range is -50 to -100°C. Additionally, there are relevant posts on the forum for discussion, for reference. Attachment: http://bbs.hcbbs.com/thread-220965-1-1.html (refrigerant)
Coolants such as liquid ammonia, Freon, and propane are not covered; I hope someone on the second floor can find more comprehensive information to study it.
Methane, nitrogen, and others are also excellent cryogenic agents
I don’t know if you’ve found it yet; if not, I can recommend a few to you
